CORRUGATED WALL PLATE.

Application led December 9, 1922. Serial'No. 605,931.

To all 'whom t mary cof/mem.'

Be it known that I, VIN'roN E. SissoN, residing at Chicago, county of Cook, State of Illinois, and being a citizen of the United States, have invented certain new and useful Improvements in Corrugated Wall Plate, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had 'to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims willy occur to persons skilled in the art.

My invention has for its object to provide an all metal car construction of novel character which is unusually strong for its weight and durable throughout, which may be conveniently and economically manu.- factured and transported, is weatherproof and which possess certain Yother desirable and advantageous features to be hereinafter described and claimed. My sheet metal wall structure applicable to box, automobile, gondola, stock or any other type of railway equipment.

The ends of railway cars are subject to considerable stress due to the shifting of the lading. These blows are imparted to the end over the entire area thereof, or to local or concentrated thrust. Corn is loaded to substantially the top of the car which causes all the blow to be imparted over the entire area of the end. Lumber is loaded to the top and upon impact the top boards shift' causing a blow to be imparted at the top of the end. Sand, chats and other plas tic loads and light pipe cause blows at the middle of the car, whereas rail, steel plates, castings and the like cause blows at the bottom of the car. From the above it will be apparent that a Irailway car end must have practically the same strength at any part thereof.

lVhile, of course, efforts are made to block the lading in the car, the heavy locomotives, the emergency air brake and the classification hump break the lading away lfrom its moorings and throw 4it against the end of the car.

A rigid end to a car, and particularly a large box car, materially Vstrengthens the entire superstructure to resist the torsional and weaving movements which not onlyrack the car to pieces, but causes leaky roofs and inoperative and leaky doors with their consequent damage claims. As itjcosts as much transport a ton of freight car as it does a a ton of lading it is imperative that the weight of the car must be kept'as low as possible, therefore, the end must be very .Y

light as well as strong. As freight cars are frequently damaged in wrecks and by other `unfair usage, any end will be damaged in service, therefore, it must be capable of being easily repaired with such meagre facilities as the railroads are equipped with 'at their outlying repair points. Y j

Car wall structures have ybeen manufactured and are in extensive use wherein a series of straight parallel corrugations are formed in the plate which terminate within the edge thereof to formlflat margins. Each corrugation is a beam and transmits any load imposed upon it to the corrugation on either side of it and to the side wall of the car. my Patent No. 1,271,234, Reissue No. 14,434 and others; the Murphy-Sisson Patent No. 1,031,571 and other patents to Murphy. y

It has been found in this present commercial end that when a local thrust deflects one eorrugation that the adjacent parallel corrugation also deflects proportionately, thereby cooperatingy to resist such thrust. Many loads, such as planed lumber and steel plate, exert a thrust along a hori- Zontal line, therefore, such thrust isexerted upon one corrugation.

The invention herein claimed consists in having the corrugaticns substantially parallel or spaced equidistantly apart, and at the same time having them curved or other wise deflected, whereby any straight line7 such as 2-2, 3 3, lO-lO or 11-11 in Fig. l crosses two or more corrugations or crosses' one of the corrugations twice. At the same time the corrugations terminate within the edge of the sheet adjacent the corner post so that thej7 constitute a series of cooperating beams.

This arrangement gives the corrugated plate additional strength and at the same time retains the resiliency and Vother v.advantages of the present commercial end.

I have shown and described my improve- Such structures are claimed in Y ment with thefcorru'gations positioned horizontally but they may be positioned vertically or obliquely. Furthermore, the wall maybe made ofrone or a plurality .of plates connected along horizontal, `vertical ork ob; lique lines. Furthermore, the construction may be applied to the'side or end wall of a box, gondola, or any other type of railway car, or the cross sectional contour of the corrugations may be of any desired contour, orpressed from either side of the plate `orpartially"from both sides, and still come within the `scope of the invention.

"In Figs. 3l, ill and 7 it will be noted that the corrugations are "spaced substantially equal distan'cesfapartandthat they are deflected from va straight line 'so that any straight line drawn across rthe plate crosses one corrugation twice orY crosses two corrugations. The corrngations vare spaced` substantially equal distances apart, it not being'necessary that theybe parallel oriexa'ct equal ldistances apartto accomplish the purpose of the invention. V Y y VInjthe drawings numerals l and 2 are the plateshaying the above described corrugations formed therein; 3- the corner post; l the end sillangle; lthe liange forming the end plate; "6` the center sills; 7 the striking casting; 8 thesde and end sill connecting pieces; 9l thelining boardsand l0 the linn ing:boardV ailing strips, all 'ot which are parts of -Ialusu'al car.

In Figs. l andrQ the corrugations l2 are formedron a reversed curve.'

Figs. 4 and 5 the corrugations 13 are formed'on'an arc and in Figs. 7 and 8 the by any straight line drawn across the plate crosses one corrugation twice or crosses two corrugations.

What I claim is:V

In a wall for railway cars, a metallic plate having a plurality of corrugations formed therein extending'from opposite edges ofthe plate, said corrugations deflected from a straight line whereby any straight line drawn across the plate crosses one corrugation at least twice or crosses at least two corrugations. o

2. vIn -a wall for railway cars, a metallic plate having a plurality of corrugations formed therein terminating within, and ex tending substantially from opposite Vedges of the plate, said corrugations deflected from a straight line `whereby any straight line drawn across the plate :crosses'one `corrugation at least twice or crosses at least two corrugations.
